Question

(Cross identities only) A large flat horizontal platform rotates at a constant angular speed ω. A person on the platform walks in a circular path of radius R0 centered on the axis of the platform with a constant linear speed v relative to the platform’s surface. The coefficient of friction between the person and the platform’s surface is µ and the mass of the person is m. How fast can the person walk if: (a) they move in the direction of rotation? (b) if they move opposite the direction of rotation?

(Please show work using cross product identies for the forces, and using polar coordinates)
Must be in polar coordinates.

Answer 1

Centrifugal forces and Coriolis effect are away from centre: Centrifugal forces are away from centre and Coriolis effect points towards the centre
